BRIDGTON — The arrival of early to mid-September’s cooler weather coincides with New England’s largest hawk migration of the year. Loon Echo Land Trust biologist Paul Miller will kick off the hawk migration season with a hawk migration talk from 6 to 7 p.m. Wednesday, Sept. 6, at the Harrison Village Library. It is the first of two free public programs to educate bird lovers, from novice to expert, on the annual migration.

Miller’s presentation and discussion will include ideal conditions for viewing, species of interest to look for, as well as helpful online resources for tracking seasonal bird migration. The library is located at 4 Front St. across from the post office.

The second program will occur from 9 a.m. to noon Saturday, Sept. 9, when Dick Anderson, former Maine Audubon director, will bring his enthusiasm for the southern hawk migration to Hacker’s Hill Preserve in Casco.

Numerous species of hawks begin their seasonal migration around this time and under ideal conditions birders have seen over 1,000 in a day. In past years many varieties of hawks have been observed along with bald eagles and osprey. Bring a lawn chair, binoculars, water and snacks.

Parking is available by driving to the top of the road into Hacker’s Hill Preserve on Quaker Ridge Road in Casco, approximately one mile from the Route 11 intersection and four miles from the Route 302 intersection. Park in the “Event Parking” area to the right of the summit.
